CUT-OFF FOR BOLTING-CHESTS.

SPECIFICATION forming part of Letters Patent No. 303,763, dated August 19, 1884. Application ilcd January', 1884. (No model.)

To @ZZ whom, it 11u14/ concern: V

Be it known that I, JOHN TODD, a citizen of the United States, residing at Lewistown, in the county of Mifflin and State of Pennsyl- Vania, have invented certain new and useful Improvements in Out-Offs for Bolting-Ohests; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

Figure 1 is a central vertical section of a bolting-chest, taken through the line w x of Fig. 2, to which my improvement has been applied. Fig. 2 represents a top plan view of the same with the flounreel removed. Fig. 3 is a detailed view of one of the cut-offs or valves.

My improvements relate to lourebolting machinery; and the invention consists in the following construction and arrangement ofthe valves located between the ilourreel and the conveyers, and which will be iirst fully dc scribed, and then set forth in the claim.

In the accompanyingv drawings, A represents a hour-reel of the usual construction. It is hung in bearings and placed over the hopper-boards B, which are V-shaped. The hopper-boards are mounted within ay bedplate,C. Beneath this bed-plate are arranged two conveyor-troughs, D E, containing the conveyers F and G, which in this case are of the spiral-vane construction, although they may be of any desired and approved form.

II are a series of valves hinged upon rods I, located over and between the two conveyer troughs or boxes. It will be noticed that the valves or cut-offs I-I form a continuation of the hopper-boards B, and that their pivotal pointis in such position that when the cut-'offs are vibrated to one side or the other (so as to form a continuation of either one of the hopper-boards B) the lower ends of the cutoff valves will project beyond the partition between the two conveyer-boxes. This arrangement prevents any lodgment or accumulation of the hour-products.

K IS are doors hinged to the bed-plate C, and which enable the attendant to get access to the cnt-oft` valves, in order to operate themv or for the purposes of renewal or repair.

L are end pieces for closing the ends of the valve-box.

Vhen it is desired to change the iiour pro ducts in their delivery from the reel through the hopper to the conveyor, so that the bolt may enter either one of the conveyers F or G, the eut-od valves H are vibrated or shifted for that purpose. In other words, when the ilour products are desired to be delivered to the conveyer F, the cut-offs H are shifted to the right, as shown in full lines in the draw ings. When the bolt is intended forthe con- -veyer G, the cut-offs are vibrated to the left,

as shown in dotted lines.

If. desired, either one or more of the cutoffs H may be shifted independent-ly of the others at any one or more points.

The cutoffs II are provided with rubber facings h, in order to make the cut-offs work closely to the partitions M between them, and thus prevent any leakage, thereby making the separation of the products more complete.

By the employment of the rubber facings to the opposite sides of the valves or cut-offs, as described, I am enabled to dispense with the usual side strips on the adjoining partitions M of the valves,which were necessary to prevent any leakage through the valves.' These side strips, moreover, are objectionable, in that the flour products accumulated upon them and prevented the proper seating of the valves.

By providing` a eut-ott` arranged over the two conveyers when arranged side by side, the iiour products are easily and conveniently changed in their delivery from one to the other conveyor atone point, thereby saving the expense and the use of apparatus for receiving the bolt at one end oi' one conveyer and transferring it back again through the other conveyer.

Having described my invention,wliat I claim as new, and desire to secure by Letters Patent of the United States, is-

In combination with the hopperboards of a flour-bolting apparatus, two conveyors, the partitions M, and a series of valves or cutoiis, pivoted, as shown, so that the lower edge of the valves will swing at either side beyond the vertical line of the partition between the conveyers, and provided with rubber facings h between the partitions and valves, whereby the usual stop or side rail Vis dispensed with.

In testimony whereof I aiitix my signature in presence of two witnesses.

JOHN TODD.
